Turbulent Dynamo Action in Binary Neutron Star Mergers

Eduardo M. Gutiérrez, David Radice, Jacob Fields +1

Binary neutron star mergers are expected to generate intense magnetic fields that power relativistic and non-relativistic outflows and shape their multimessenger signatures. These…

AthenaK Simulations of Magnetized Binary Neutron Star Mergers

Jacob Fields, David Radice

We present new numerical-relativity simulations of a magnetized binary neutron star merger performed with AthenaK. The simulations employ a temperature- and composition-dependent t…

Magnetic Field Configurations in Binary Neutron Star Mergers II: Inspiral, Merger and Ejecta

William Cook, Eduardo M. Gutiérrez, Sebastiano Bernuzzi +6

We perform a series of simulations of magnetised Binary Neutron Star mergers, with varying magnetic field topologies in the initial data, as well as varying Equations of State, and…

Investigating the Impact of Higher-Order Phase Transitions in Binary Neutron-Star Mergers

P. Hammond, A. Clevinger, M. Albino +10

In this paper we investigate quark deconfinement in neutrons stars and their mergers, focusing on the effects of higher orders for the phase transition between hadronic and quark m…

Magnetic Flux Emergence in Binary Neutron Star Remnants

Jacob Fields, David Radice, Peter Hammond

Using high-resolution AthenaK simulations of a twisted toroidal flux tube, we study the flux emergence of magnetic structures in the shear layer of a hot massive neutron star typic…

Magnetic Field Configurations in Binary Neutron Star Mergers I: Post-merger Remnant and Disk

Eduardo M. Gutiérrez, William Cook, David Radice +6

We present a suite of general relativistic magnetohydrodynamic (GRMHD) simulations of binary neutron star (BNS) mergers performed with the code GR-Athena++. We investigate how a di…
